Abstract
Abstract A new spin crossover iron(II) complex, [Fe(H2L2-Me)2]Cl2·2-PrOH·0.5H2O (1), has been prepared, where H2L2-Me = (2-methylimidazol-4-yl)methylidene)histamine. The complex is a chiral molecule due to octahedral coordinations of two tridentate ligands, they are linked by the hydrogen bonds of NH···Cl−···HN through Cl− ion into a chiral one-dimensional (1D) rod, and further the chiral rods with the same chirality are stacked to form a chiral crystal (conglomerate). The solvated sample showed a two-step SCO, and the desolvated sample showed an abrupt one-step SCO at T1⁄2=180 K.
